The Unidad de Operaciones Especiales (Special Operations Unit - UOE) was the elite special operations force of the Spanish Navy and Marines from 1967 to 2009. In June 2009, the unit was absorbed into the newly formed Naval Special Warfare Force (Fuerza de Guerra Naval Especial). The UOE, which was formerly garrisoned in the Tercio de Armada in San Fernando, Cádiz, operated under the direct control of the Admiralty and Naval Special Warfare Command. It was thought to comprise approximately 100 men organized into three Operational Teams (Estoles) as well as command and support personnel.
